'Patenteapea 5, i905.

Be it known that I, WILLIAM T. HANNA,ja. citizen ofthe United States of.America, and

ya,I 'efsidentof Cincinnati, county of Hamilton,

State ofj ,Ohi, have invented certain newl and useful Improvements in Vehicle-Hubs, VAof.

A which the following isa specification.

The object oflmyinvention is avehicle-hub l especially adapted for use in automobiles, so

that thewheel may be removed readily and as' `readily replacedin its bearings ,for the purf pose. of repairing the, tire or" other parts' ofthe wheel.

Referring to the drawings, in which like parts are indicated by similar reference-letters in the various views, Figure 1y is a 'perspective view of the hub embodying myinvention, one

of the journal-bearings being shown in section.

Within which the axle fits.

Flg. 2 is a central sectional'view of thehub.A Fig/3 is a detail side elevation ofthe member of the coupling which joins the hub to the main shaft. Fig, 4'is a detail perspective'view'of the central axle of the hub. Fig. 5 is a front elevation f the coupling shown in Fig. 3;- Fig. 6` is a perspective viewof the sleeve Referring to the parts, axle A has a longi-y tudinal central bore a and upon its periphery a longitudinal groove a', which is centrally. intercepted by a bridge d2.. Within groove a', upon opposite sides of the :bridge-fa, keys- 'B B fila- Sleeve C has a central.' bore to t,

snugly over axle A and a longitudinal ,grooveI -Shelli) has averticalcircular flange d and an shell Dts.

* 45 n engage collars o c. of the hub l threaded anges ve "ef c to register with ygroove a and to formtherewith a keyway for keys B B'. i The ends' .c' o2 of the. sleeve are reduced to form s'll'oulders c3 lc,'the ends being made octagonal and being internally sc rewfthreaded.

y.Over thefsleeveC ts the external housin of, the hub, which consists of'shellsvD D.

elongated annular flangey over which the similar to flange d. Shells D D lhave inwardly-projecting octagonalanges dsd to C' and to abut against shoulders c3 c4 thereof. Between the 4flanges d 'd2 the spokes areltojbe held"` in the usual manner. g The. hub is held u'pon'thefaxle A by .means of nuts 'E E', which,` have., external screw-v threads uponfthe ends of the4 sleeve C and 'of the sleeve'Cvand the shells D D. has teeth e,

the teeth f of .the member `F of a coupling. The member F of the coupling has `likewise a4 stud f The ysleeves E E grooved uponv theirexterio'r to form ball- G, -belngprovided for the nut E.` The coupling F is held in mesh with the teeth e* by means' of a bolt H, which extends'through the bore a; of'the axle and receives uponits enda nut L, as illustrated in Fig. l. bolt H bears against a cap K, which has teeth v A'similar toteeth f toimesh withv teeth efupon nut E. Theperiphery of capK is similar to nut E to form ball-bearing su rfaces.

Which'are to be engaged byI universal to en, yag e the groove a. and the coupling Fare bearing surf-aces.

the source of power. When it is desired to remove the Wheel from its bearings, nut L is' removed from the bolt lI jI and the .bolt is then Withdrawn from. the

withV the bearings the What I claimisf 1. The combination of a short axle having in its periphery a longitudinal groove inter'- cepted` by a bridge, a hub vand having a groove 'to' forma keyway with vthe groove in the axle, key way upon oppositersides of the bridge and nuts to engage the hub andtoa .12..

to t over 'the axle ut against the keys.

in 'its periphery a.V

S seated. in the key?4 Ioo Vkeys seated in the keyway upon opposite sides i of the bridge, nuts to engage the hub and to abut against the keys and having bearing-sur- 'faces formed `upon their exteriors in combination with two journal-bearings adapted to receive the nuts and a coupling to engage the hub at one side to impart rotation thereto.

3. The combination of a short axle having in its periphery a longitudinal groove inter? cepted by a bridge, a hub consisting of an in`- terior sleeve and an external housing, the sleeve to fit o ver the axle and having a groove to form a keyway with the groove in the axle, keys seated in the way upon opposite sides of the bridge and nuts to engage thesleeve and abut against the ends of the housing and against the keys..

4:. The combination of a short axle having in its periphery a longitudinal groove intercepted by abridge, a hub consisting of an interior sleeve and an external housing, the' vsleeve to fit over the axle andhaving a groove to form a keywayvwith the groove in the axle, thehousing consisting of two shells, onehaving an elongated annular Hange to fit over the sleeve anda transverse iange, and the other shell fitting over the annular iiange ofthe first Shell and having a transverse ange to form with the aforesaidtransverse flange a way'for the spokes and nuts to engage the sleeve and to bearl against the outer ends of the shells.

v5. The combination of a short axle having in its periphery, a hub consisting of an interthe hub and the keys to lock the hub upon the axle, the nuts ybeing formed with bearing-surfaces for seating in the journal-bearings, caps for engaging the nuts and means for locking ,the caps upon the axle.
